NIPPERS.

SPECIFICATION forming part of Letters Patent No. 451,668, dated May 5, 1891.

Application filed December 17, 1890. Serial No. 375,018, (No model.)

To all whom it may concern.-

Be it known I, DAVID A. HAMILTON, a citizen of the UnitedStates, residing at Heppner, in the county of Morrow and State of Oregon, have invented new and useful Nippers, of which the following is a specification.

The invention relates to improvements in nippers.

The object of the present invention is to simplify and improve the construction of nippers, increase their cutting power, and prevent their cutting-j aws coming in contact with other parts of the nippers, and thereby enable the cutting-edg'eto last for a considerable length of time.

A further object of the invention is to enable the cutting-jaw to be readily removed when worn or broken.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a pair of nippers constructed in accordance with this invention. Fig. 2 is a side elevation, partly in section, the jaws being closed. Fig. 3 is adetail perspective view of the cutting-jaw. Fig. 4 is a plan view of the jaws.

Referring to the accompanying drawings, 1 and 2 designate similar-shaped members of a pair of nippers secured together intermediate their ends by a rivet 3 and adapted to be opened and closed on the rivet in the usual manner, the member 2 being provided with the ordinary inward-bent end at, arranged to be engaged by the adjacent end of the other member to prevent the handle portions of the members entirely closing. The upper portions 5 of the members are similarly curved, and the member 1 is provided at its end with a fiat integral jaw 6. The jaw 6 is provided with a slightly-concaved edge 7, which is not constructed for cutting, and the jaw 6 acts in conjunction with a removable cutting-jaw 8, which is provided with abeveled cutting-edge 9, arranged at an angle and forming a point at one side of the jaw. During the operation of cutting the removable cutting-jaw passes beneath the stationary jaw 6, the cutting-edge exerting a shearing action. The upper end of the member 2 is provided with an integral plate or flange 11, which has its outer edge 12 rabbeted and provided with threaded perforations 13, adapted to be engaged by screws 14. The screws 14 secure to the flange or plate 11 the cutting-jaw 8, which is rabbeted on its lower face at its inner edge 15 and fits snugly in the rabbeted portion of the plate or flange 11, and is provided with countersunk perforations 16 to receive the screws 14:- By this construction the cuttingjaw may be readily removed when it is desired to sharpen the same or to provide another jaw.

The nippers are simple and inexpensive in construction and are of a special value in horse-shoeing, as the shearing action of the cutting-edge will effectually prevent breaking or splintering the hoof of an animal.

What I claim is The nippers comprising the similar members 1 and 2, pivoted together and having their upper portions 5 curved, the member 1 being provided with an integral non-cutting jaw having a slightly-concaved edge, the section or member 2 being provided at its upper end with an integral plate or flange 11, having its outer edge rabbeted and provided with threaded perforations, the on tting-j aw having its inner edge rabbeted and provided with countersunk perforations and its outer cutting-edge arranged at an angle and forming the point at one side of the jaw, and the screws or rivets 14, arranged in the said perforations, substantially as described.

In testimony that I'claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

DAVID A. HAMILTON.
